A. Set up an internet gateway. Update the route table on the subnets to use the internet gateway to route traffic to Amazon S3 
B. Set up an S3 VPC gateway endpoint. Update the route table on the subnets to use the gateway endpoint to route traffic to Amazon S3. 
C. Set up additional NAT gateways in each Availability Zone. Update the route table on the subnets to use the NAT gateways to route traffic to Amazon S3.  
D. Set up an egress-only internet gateway. Update the route table on the subnets to use the egress-only internet gateway to route traffic to Amazon S3.
